• 4 Week Implementation Life Cycle– Week 1: IT will create and test the AD GP settings.– Week 2-4: Tier 1s will apply and test each GP to their
respective AD Organizational Unit (OU) and present feedback to IT. For settings that present a change for their end-users Tier 1’s should communicate those changes in advance to their user community. IT will assist in developing appropriate communications.
– Week 5: IT will evaluate any feedback given and make necessary modification before applying the settings at the campus wide level.
